![]() The subnet mask of the printer is actually configured properly, and the This example comes from an HP printer that has a bug in its SNMP implementation. Will give a status window similar to the one above. That the subnet mask has zero bits in the left half clicking on the link The network oval with a discontiguous subnet mask. That there's a problem with the subnet mask. Why do network labels sometimes have a "/2*"? This error is shown in the status window. This example shows a device whose IP address and subnet mask are set to Normally, the address line contains the IP address and the subnet mask. Hold on a link: the status window resembles the figure at the right. Intermapper points this out when you click and ForĪ subnet mask that has zero bits interspersed with the one bits in the left half of the value is oftenĪ configuration error. Of bits in the subnet mask, and uses the notation of "/24" to IntermapperĬan then use the convention that a subnet mask is described as the number ![]() In usual network configurations, a device's subnet mask contains oneīits in the left side of the number, and zero bits on the right. What does it mean when Intermapper says a "subnet mask is discontiguous"? To do this, Get Info on the affected device andĬheck the "Ignore Interface Errors" or "Ignore Interface The error reports are bogus, you can instruct Intermapper to ignore theĭiscards and/or errors.
